Version 6.1.0h NOTE: This software conforms to the Fibre Channel Standards in a manner consistent with accepted engineering practices and procedures. Supersedes Fabric OS 6.1.0g released in November, 2008. Effective date January 2009 Description Fabric OS 6.1.0a integrated many new features that are listed below. Fabric OS 6.1.0h also provides these same features, but does not add any new features since 6.1.0a.

Traffic Isolation Zones over FCR This enhancement enables traffic isolation across EX ports and VEX ports. This benefits applications like Tape Pipelining and Fast Write that traverse VE ports where customers want to control the exact path and ports that are used. Port Mirroring Fabric OS 6.1.x adds support for Port Mirroring to 8-Gb ports.

LDAP FOS 6.1 includes enhancements to LDAP allowing Active Directory server roles to be mapped to the various switch roles. Parameter added for slotshow command An optional –m parameter has been added for the slotshow command, to display Model Names for each blade installed in a DC SAN Director or 4/256 SAN Director chassis.

Power supply requirements for Director blades Table 4 lists power supply requirements for Director blades to provide full redundancy (220V power is assumed). IMPORTANT: Director blades must meet minimum Fabric OS levels to operate in Director chassis. For example, the FC8-32 is not supported in the 4/256 SAN Director with Fabric OS 6.0.x.

Topic Description Traffic Isolation over FCR • All switches and Fibre Channel Routers both in edge and backbone fabrics must be running Fabric OS 6.1.0 in order to support this feature. • It is essential to have “fail-over” policy enabled in all edge fabrics that are part of the Traffic Isolation Zones, in order for the proper functioning of Traffic Isolation over FCR.

Closed defect summary Solution If a device tries to login to an NPIV port using a port WWN, which Fixed in Fabric OS 6.1.0 is already used by another device that has already logged in, the switch simply drops the new login (FDISC) request instead of rejecting Incorrect FRU Update date is received for Brocade_Chassis class.

Closed defect summary Solution On disabling the proxy switch (FOS 6.0 ), no event received on the Fixed in Fabric OS 6.1.0 SMIA agent side. When HA sync was stopped, a SAN Director 2/128 did not output Fixed in Fabric OS 6.1.0 the FW-1433 message.

Closed defect summary Solution The switch status is shown as Healthy with one core blade even when Fixed in Fabric OS 6.1.0 the policy is set to show as marginal on removal/failure of a core blade. FICON Tape Pipelining with specific tape devices results in block count Fixed in Fabric OS 6.1.0 mismatch errors.

Closed defect summary Solution With FC fastwrite zones (connecting local hosts to remote devices) and Fixed in Fabric OS 6.1.0g. non-FC fastwrite zones (connecting local hosts to local devices) going Workaround: Run portdisable and to the same devices, not all host ports receive RSCNs after device logon portenable on the initiator port to and link down.
